Sulphur dioxide - SO2

In
2008, the mean concentration of sulphur dioxide (SO2)
measured during the winter
period was higher than the mean annual concentration at all measuring points. Mean annual SO2
concentrations
and mean winter period concentrations in excess of
the limit values
set for ecosystem protection were observed in
major urban centres.

According to the available data, mean daily concentrations of SO2
in excess of the limit value were observed in the City of Skopje only in 1998, 1999 and 2006 due to the operation of facilities for heat and energy production in the winter period, industry and heavy traffic. Such
exceedances, however, were not found in Macedonian cities.
